Chelsea host Paris Saint-Germain in the Champions League last 16 tonight, where they trail 2-1 from the first leg.

John Obi Mikel scored a vital away goal in the French capital, but the Ligue 1 champions will still be confident of going through after Zlatan Ibrahimovic and Edinson Cavani gave them a slender advantage.

This is the third consecutive season these two sides have met in the Champions League knockout stages, with each side going through once.

But who's likely to start tonight? And what has each camp said in the build-up?

7. Recent form

8. Chelsea's key man

Diego Costa

He's scored 10 goals in his last 13 appearances, but the key to success tonight might be more underhand skills.

PSG come into this game as slight favourites to go through, and Chelsea may need to get under their skin to get the result they need. Costa, as well as being in great form, is the man to rile up the PSG players.

9. PSG's key man

Zlatan Ibrahimovic

Could it really be anyone else? The big Swede is approaching the end of his time in France, his contract is up at the end of the season and it will not be renewed. But Ibrahimovic is as motivated, and dangerous, as ever.

Against a defence lacking it's leader and best member, John Terry, Ibrahimovic may fancy his chances of being the difference tonight.

Hiddink on Hazard: “When Eden was playing away in Paris, he was in that period just coming back from a rather severe injury which we could not ask him to be at top fitness.

“Now we are some weeks further into his game fitness and, of course, he can and must show tomorrow what he’s capable of.

"That’s more than, of course, in the away game.

“But the reason he was subbed was to avoid going into a danger zone after coming back from injury.

"You cannot expect to be on top of your game at that stage, but we are thinking he can deliver now in full fitness.”

Blanc on recent trips to Stamford Bridge: "I don't think we have to think about what happened in the last two matches played here.

"Every game has its own story. We have our own ambitions and we want to qualify, but it's the same for Chelsea. I think it will be a very difficult match, more difficult than last season. If we have done it once, we can do it again.
